I ordered 2 of the Go Everywhere passes and just received my email today. From the looks of it, these should be easily transferable, as all they require is a code and e-mail address. The cities included are: LA, Boston, Chicago, Vegas, Miami, NY, Oahu, Philly, Orlando, San Diego, San Francisco, and Washington DC, and a general California pass. You can check out the all the included attractions on the Go City website.
I'm selling each individual city at 70% of the online price. These are a great value, and can be especially useful now before Yeshiva Break. As an example, the Go Pass for California includes San Diego Sea World (normally $91.99), the San Diego Zoo (normally $58.00), Six Flags (normally $75.18), and more! All the passes expire end of 2020.
